Description

Refrigerator in the wall

Technical field

The utility model relates to the structure of refrigerator and builds the adaptation technique field with external wall of house, relates in particular to refrigerator in a kind of wall.

Background technology

1910 in the world the domestic refrigerator of First compression-type refrigeration come out in the U.S., nineteen twenty-five, Sweden developed the family expenses absorption refrigerator, the fifties in last century, latter half, the Household hot refrigerator began to put into production ... develop into today, refrigerator is classified by refrigeration principle: (1) in the world 91～95% refrigerator belongs to compressor type refrigerator, and its refrigeration system is comprised of compressor, condenser, device for drying and filtering, capillary (throttling arrangement), evaporimeter; The motor compressor work done, cold-producing medium is flowed in system, the refrigerant vapour of HTHP (more than ten atmospheric pressure) is discharged into the condenser that is installed in case shell outside, dispel the heat there, liquefy, cold-producing medium enters evaporimeter in the refrigerator with liquid form, heat in evaporimeter in evaporation gasification and the absorption refrigerator makes refrigeration in the refrigerator; Cold-producing medium is general freon in the past, because it can damage the ozone layer, is eliminated gradually now, use other cold-producing mediums instead, but principle is the same.(2) absorption refrigerator accounts for market 5 percent, is made of the refrigeration system of sealing generator, rectifier, condenser, evaporimeter, absorber, lime set tank; Be filled with ammonia, water, three kinds of components of hydrogen in the system, the wherein high steam of the ammonia liquefaction of in case shell external condenser, dispelling the heat, liquid ammonia heat in evaporation gasification, the respiratory box in the evaporimeter in refrigerator produces refrigeration.(3) the electric heating refrigerator is borne semiconductor refrigerator; It is to PN type semiconductor, passes to direct current, utilizes the refrigerator of the pyroelectric effect realization refrigeration of semi-conducting material.In addition, also have chemical refrigerator, electromagnetic oscillation refrigerator, adiabatic demagnetization refrigeration refrigerator, radiation refrigeration refrigerator, solid coolant refrigerator etc.

If press refrigeration modes (pressing air circulation mode in the case) classification of refrigerator, can be divided into direct-cooling type and air-cooled (claiming again indirect-cooling) refrigerator.Direct cooling refrigerator is by evaporimeter, and directly heat is lowered the temperature in the respiratory box; And evaporimeter and fan are housed in the air cooling type refrigerator case, fan air-supply is forced the case inner air convection, promotes heat in the evaporimeter respiratory box, realizes uniform decrease in temperature in the case.Divide if press refrigerator purposes (pressing Storage Requirement), can be divided into refrigerating box, household freezer and household refrigerator-freezer.Refrigerating box be used for to be stored does not need the food that freezes, sets about 4 ℃-5 ℃ of case temperature scope; Household freezer is suitable for food product refrigeration, set the case temperature below-18 ℃ (refrigerator temperature set because of store, frozen food is different, refrigerator manufacturer difference has different, but substantially close.In the application's discussion take above-mentioned setting case temperature as example).Refrigerator also can be classified by chamber door what, refrigerating capacity, Defrost mode etc., does not give unnecessary details one by one.

There are some problems in the refrigerator prior art, wherein following 4 important, have much room for improvement:

The first, the refrigerator environment temperature concerns energy-conservation.

For refrigerator energy-saving, domestic consumers have noticed that refrigerator should be placed in indoor stow away from heat, ventilation shady spot.Brainstrust is then pointed out theoretically; the environment temperature of refrigerator is that refrigerator environment temperature height has a direct impact refrigerator power consumption: the refrigerator environment temperature raises; refrigerator outwards heat radiation is slow; the temperature inside the box descends slow; and the cold that outwards scatters and disappears in the case is many, keeps the low temperature set in the case difficult, causes the refrigerator available machine time to lengthen; shorten downtime, causes that power consumption increases.The prompting of general refrigerator experimental data, the every raising of refrigerator environment temperature 5 degree Celsius will increase by about 25% power consumption.Otherwise, the identical and refrigerator environment drop in temperature of other physical conditions, refrigerator power consumption is then with corresponding minimizing.But about 20 ℃-25 ℃ of Modern Family's comfort zone, domestic refrigerator is placed in indoor, and the refrigerator environment temperature is room temperature, sets the case temperature with refrigerator cold-storage case or refrigerator freezing case and compares the higher temperature difference of existence, the temperature difference that this is higher, the power consumption higher with refrigerator concerns.If the room temperature that the environment temperature of refrigerator compares decreases, will realize refrigerator energy-saving.

The second, the utilization of cold outdoor air.

If refrigerator is placed on indoor, about 20 ℃-25 ℃ of the room temperature of Modern Family's comfort standard, indoor environment temperature is the environment temperature of refrigerator, should not change; Outdoor environment temperature is referring to table 1.Table 1 has been enumerated in the world annual 12 months the monthly mean temperature in 10 major country cities (largest city or the capital that comprise 5 permanent members of the United Nations and all the other 5 developed countries).

The annual monthly mean temperature statistical form in ten major countries in table 1. world city (degree centigrade)

It has certain representativeness for quite vast region temperature Change scope in the world.If take some month the temperature on average in some cities wherein as one " monthly temperature ", table 1 has been added up 120 " monthly temperature " altogether.Wherein

(1) 116 " monthly temperature " is lower than 25C, accounts for 96.6%;

(2) 104 " monthly temperature " are lower than 20C, account for 86.6%;

(3) 80 " monthly temperature " are lower than 15C, account for 66.6%;

(4) 60 " monthly temperature " are lower than 10C, account for 50%;

(5) 39 " monthly temperature " are lower than 5C, account for 33.3%;

(6) 22 " monthly temperature " are lower than 0C, account for 18.3%.

As seen, the territory is in the overwhelming majority time immensely in the world, and outdoor environment temperature is lower than indoor environment temperature.

With the refrigeration source of cold outdoor air as refrigerating equipment, especially in northern area winter, some imaginations once were suggested for many years, were difficult to for various reasons obtain the coml extensive use.Need to explore a kind of more simple and easy structure and method, cheaply directly use this a large amount of naturally occurring cold outdoor air and participate in refrigeration for refrigerator.

The 3rd, refrigerator has occupied valuable careat and space.

Refrigerator is one of household electrical appliance that take careat and space maximum, and its front and back also need keep certain distance with indoor wall or other furniture up and down in addition.In the increasingly expensive situation in short supply in usable floor area and space, both having kept the function of refrigerator in the family room of big and medium-sized cities, economized out again its occupied careat and space, is that people's institute expects.

The 4th, refrigerator also is the highfield.

According to expert introduction, be a highfield during refrigerator work, the magnetic field maximum that usually discharges with side behind the refrigerator or below.The different wave length that refrigerator discharges and the electromagnetic wave of frequency have certain influence to people's nervous system and physiological function; Electromagnetic penetration power is extremely strong, can see through body surface and go deep into deep tissues and organ, makes it to suffer damage.Reducing and avoid refrigerator magnetic field on impact and the infringement of human body, also is one of problem of often considering of people.

People once proposed respectively such-and-such scheme for this reason.

Propose refrigerating equipment is placed on the open air such as the scheme that has, or be installed on the window.Although but the housing of refrigerating equipment can be used the quality material manufacturing, expose year in year out after all the outdoor service life that affects; Temperature is suitable for use about the refrigerating equipment design temperature, temperature is low, and then the food that does not need to freeze stored of refrigeration can be frozen, the temperature height more things turn out contrary to one's wishes; Inconvenience from refrigerator access food, perhaps affects the indoor lighting sight indoor.

The scheme that has proposes, with lower wall conduit cold outdoor air is introduced indoor connection refrigerator, the fitted shaft flow fan is squeezed into refrigerator with cold air, pass in the case, Bas Discharged after blast pipe through drawing in case and another lower wall conduit will be replaced in case under ventilating fan cooperates again to outdoor atmosphere, circularly cooling like this.This air cooling system has certain-length into and out of pipeline, needs the brill wall to make under the hole and manages, and operates simple and direct not.And refrigerator is placed in indoor caused variety of issue and unresolved.

The scheme that has proposes compressor, condenser are separated from the refrigerator of routine setting, places the open air as off-premises station, links to each other by the wall conduit wire with refrigerator remainder as indoor set, with minimizing refrigerator indoor radiating, noise.But this minimizing is very limited, is not restricted to compressor and condenser because participate in the device of refrigerator heat radiation, in fact still is placed on the main body, machine chamber, air blast of indoor refrigerator so that air-flow guiding elements etc. are all relevant with the refrigerator heat radiation.And refrigerator is placed in indoor more caused problems and still exists.

Also have some schemes to propose refrigerator is embedded in the depression of wall; Perhaps embed in the kitchen cabinet; Perhaps being built in two partition walls between the room, is not the exterior wall in house, and in the partition wall that is built between kitchen and the parlor, so the refrigerator opposed access door is can be from kitchen and simultaneously access of parlor food.These schemes can make indoor beautifying, save to a certain extent the careat space, but in fact refrigerator is also indoor, and the environment temperature of refrigerator or room temperature also are difficult to tackle above-mentioned some problem.

In addition, for the impact of refrigerator electromagnetic radiation, the expert advice refrigerator is not placed on the place that the people such as parlor often stay, and is placed on the kitchen and will avoids when refrigerator work near it as far as possible yet or avoid storing food when refrigerator work as far as possible; And through dust catcher commonly used the position dusts such as refrigerator radiating tube are sopped up because dust more multiple electromagnetic radiation is just larger.But its effect is limited, for the solution of above-mentioned other problems also without benefiting.
